Question 4

refers to the size or strength of the force. It is commonly expressed in newton (N) for Meter-Kilogram-Second (MKS) system, dyne (dyn) for Centimeter–Gram–Second (CGS) system and pounds (lbs) for Foot– Pound–Second (FPS) system. In the International System of Units (SI), newton is commonly used which is named after Sir Isaac Newton, an English physicist and mathematician.
